A consumer report counted 727272 low-quality, 112112112 medium-quality, and 711711711 high-quality computers based on a random sample. The report went on to say that all computers, regardless of quality, are packaged identically and sold at the same price.
Use the observed frequencies to create a probability model for the quality of the next computer purchased.

I think it is very large question please place a short one
Answer:
Let us first jot down all the data given in the question;
Number of low quality computers (LQ) = 72
Number of medium quality computers (MQ) = 112
Number of high quality computers (HQ) = 711
∴ Total number of computers found in a random sample = 72 + 112 + 711 = 895.
∴ To find the probability of purchase for each category of computers, we use the following formula;
\frac{no.-of-computers-n-a-particular-category}{total-number-of-computers}
total−number−of−computers
no.−of−computers−n−a−particular−category
So,
P(LQ) = 72/895 = 0.08
P(MQ) = 112/895 = 0.125
P(HQ) = 711/895 = 0.794
Ans) Probability of purchase of a low quality computer, a medium quality computer, and a high quality computer are 0.08, 0.125, and 0.794 respectively
